Combining decision support models for infrastructure asset management

Abstract

Based on the typology of several decision-making models encountered in infrastructure asset management, in particular for urban networks and protective structures, this article compares different models developed for decision support. It recalls the importance of defining decision-making contexts and shows the necessary complementarity between multi-criteria decision support methods, economic approaches such as cost-benefit analysis (CBA) and deterministic models whose results relevance must be analyzed according to the quality of the data used.
